1. To prevent electrical shock, disconnect all power coming to heater at main service panel before wiring or servicing.

2. All wiring must be in accordance with the National and

Local Electrical Codes and the heater must be grounded as a precaution against possible electric shock.

3. Verify the power supply voltage coming to heater matches the ratings printed on the heater nameplate before energizing.

4. This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces.

5. Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock, fire, or damage to the heater.

Operation

1. Rotate the thermostat fully clockwise. This should energize the heating elements and cause warm air to flow from the hot air discharge at the openings in the bottom of the grille.

NOTE: This heater is provided with a fan delay control that allows the heating element to warm prior to the fan coming on. This delay will also allow the fan to operate for a short period after the heating element has been turned off to remove the residual heat from the heater.

2. After the operation check, rotate the thermostat to the desired position to obtain room comfort.

NOTE: For best results, the heater should be left “ON” constantly during the heating season because the thermostat, when properly set, will maintain the desired temperature.

Important Information

and marked “reset”. The red reset button can be seen through the front grille when the heater is installed. To reset, allow the heater to cool, then push the red button that is visible through the hole in the fan panel. The heater should immediately return to normal operation.

CAUTION

!

OPERATION OF THE MANUAL RESET SAFETY THERMAL LIMIT

CONTROL IS AN INDICATION THAT THE HEATER HAS BEEN

SUBJECTED TO SOME ABNORMAL CONDITION. IT IS RECOM-

MENDED THAT THE HEATER BE CHECKED BY A REPUTABLE

ELECTRICIAN OR REPAIR SERVICE TO ENSURE THE HEATER

HAS NOT BEEN DAMAGED.

Once each year the heater should be cleaned to remove dust and other foreign material which has collected during the heating season. This is a simple operation when performed as follows:

1. Turn off the electric power at main line switch (or remove all fuses) to disconnect electric power from the heater.

THIS IS IMPORTANT.

2. Remove thermostat knob.

3. Remove front cover by depressing plastic snap tabs with a flat bladed screw driver as shown in Figure 5. Release both tabs on one side then rotate the front cover off of the fan deck.
